ilumisys, Inc., and parent company Altair Engineering continue to invest in the success of the LED industry by bringing quality LED products to market through licensed companies

TROY, Mich. – March 23, 2011 – ilumisys, Inc. (http://www.ilumisys.com), developer and producer of next-generation solid-state lighting technology, announced today that it has granted a license for light-emitting diode (LED) fluorescent tube replacements to Lumenor Energy Services, a lighting retrofit company based in South Florida.

“This partnership will allow us to expand our portfolio of LED retrofit products and continue to provide our customers the best options in the industry,” said David Matten, managing partner for Lumenor Energy Services. “Our mutual commitment to retrofitting existing infrastructure to be more energy efficient through the use of quality LED products will enable Lumenor and ilumisys to be at the center of the rapidly growing LED industry.”

Since the price and performance of LED fluorescent tube replacement products vary, the ilumisys licensing program allows Lumenor to provide a larger range of retrofit products to the market. The licensing agreement provides for royalty payments in exchange for rights to manufacture and sell products covered by the patent portfolio of ilumisys’ parent company, Altair Engineering.

By providing licensees access to its expanding patent portfolio, ilumisys believes that the pace of both LED product development and installation will continue to accelerate.

“The LED marketplace is positioned for tremendous growth, and our goal with the licensee program is to support the industry by helping credible companies, like Lumenor, offer a wide-range of LED products,” said Dave Simon, president of ilumisys. “ilumisys is strongly focusing on manufacturing and expansion efforts to ensure it will be able to meet the needs of the industry in partnership with a number of companies.”
